WebEx takes over the Join/Add con-call button on my S4, as others have posted: https://supportforums.cisco.com/discussion/121961. What can be done to keep Cisco WebEx app but be able to manage con-calls? Screen shot attached; my corporate help desk is stumped...advised abandoning Cisco app (how's that for an answer; we have a Citrix relationship, too, so I'm being sentenced to GoToMeeting; next it will be MS Lync instead of Jabber!)
I also have this problem and need resolution!
